WILLIAM JENKINS DAWSON, OF LAWRENCE, KANSAS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 264,634, dated September 19, 1882,

Application filed February 7, lSSl. (No model.) I

To all whom it may concern t Be it known that I, WM. JENKINS DAWSON, of Lawrence, in the county of Douglas and State of Kansas, have invented a new and Improved Car-Coupling; and I do hereby declare that the following is a full, clear, and eXact description otv the same, reference being had to the accompanying drawings,'t`orming part of this specification, in which- Figure l is a perspective view of my improved car-coupling. Fior. 2 is a central vertical section ofthe same; and Fig. 3 is a Itop view with the cover of boX open, showing devices tor supporting coupling-pin in position for automatic coupling. My invention relates to improvements in car-couplings; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth.

In the accompanying drawings, c represents a draw-head ofthe usual construction, the npper face of which is provided with the longitudinal ribs b I), secured thereto.

c represents a transverse piece, connecting the rear ends of the ribs b and secured thereto, forming a box or receptacle, b', on the upper face of the draw-head, open at its top.

d represents a cover for the open top ot'said boX, the rear end of said cover being` hinged to the ribs b bby means of the eye-plates e e, secured to the upper face of the cover d near its rear end, and rod or pintle j','passin g through the eyes of the eye-plates e and corresponding holes made in the ribs b.

g represents an oritice made in the cover for the passage of the coupling-pin t'.

7g 7L' represent hollow Han ges or cylinders, secured to the upper and lower faces of the cover, over and under the orifice g, to guide the coupling-pin t in its movements.

lr t represent two elbow-levers, each pivoted by pins 7c27t3 to the upper face of the draw-head, and passingthrough slots k6 in the ribs b, and terminating in handles 767, and having the semicircular arms 765, provided with straight edges adapted to close when the elbow-levers are moved in one direction, and close the orifice g' in the top face of the draw-head and support the coupling-pin, and when the elbowlevers are moved in the opposite direction to open and allow the coupling-pin to pass down into the draw-head and through the link e.

ka 7d represent pins passing' through the. semicircular heads ot' the arms 7c, the lower ends of which bear against the upper face ot' the draw-head to preventt he lower faces of the arms 765 from resting on the upper face of the draw-head and allow the escape ot' water through the oritice g. The rear end of the arm 7s', is provided with a downwardly-proiecting pin, 7c, which engages with a curved slot, kl", in the rear end of the other arm, 7c, so that. any motion imparted to one ot' the arms 7c4 will impart a similar motion to the other.

m m represent rods attached to the. arms 7a4 7a4 of theelbow-levers outside the draw-head, thence curved downwardly, with their outer ends passing through holes in the flange at the mouth of the draw head, and projecting slightly beyond said flange, for a purpose herein-aft er set forth.

a represents a yoke or bail provided with parallel vertical eye-rods n', by means ot' which the bail is pivoted to the outside and upper part ot the draw-head by pins n, whereby a swinging motion can be imparted to the bail to and from the mouth of the draw-head, to raise and lower the link when ears of different heights are to be coupled, by means ot` the levers a2, secured to the bail.

0 represents the lower horizontal transverse rod or bar of the yoke, adapted in the swinging movement of the bail to pass under the mouth of the draw-head.

o represents a rod or bar parallel to the rod o, and secured at its ends to the vertical eyerods n', and adapted, when therods a are vertical, to lie in a horizontal groove in the face ofthe draw-head.

ln coupling cars of ditt'erent height, the coupling-pin having been inserted through the link in the lowest draw-head, the bail in said draw-head is raised by the lever a2, raising the link so as to enter the opening inthe opposite higher draw-head. It' one draw-head were much higher than theother, with an ordinary bail having but one lower transverse rod, theI tendency would be., in coupling the cars,it' said rod were raised as high as the points of suspension of the bail to break said bail by 10o the impact of the drawheads, or to throw over backward the bail and prevent the coupling ofthe cars.

By constructing my bail with two horizontal parallel cross-bars, 0 o', the former supporting the outer end ot' the link, the rod o rst comes in contact with the opposite drawhead, always below the points ot' suspension of the bail, and insures the downward movement of the bail. In coupling cars of different heights, should the bail be raised above its points ot' suspension, p p represent springs coiled around the inner ends of the pins a', whichsusl'iend the bail, the opposite ends of said springs bearing against the bailor handle, the function of the'springs p p being to force the. bail down when raised by the levers.

The above construction ot' bail may be applied to the inside of the drawhead, as well as the outside, with slight differences in the details of construction, without departing from the'spirit of' my invention.

To hold the link horizontal in a draw-head, with cars ot' the same height, I employ a spring-dog, 9, hung` on the transverse rod r', secured to the opposite sides ot' the drawhead. The dog r is composed ofthe two curved arms r" r2, the latter bearing on the inner face ofthe top ot' the draw-head, and the form er, r, pressing against the upper face ot' the rear end ot' the link and holding the latter hori zontal in coupling the cars. p

That I claim as new, and desire t0 secure by Letters Patent, is-

l. The combination, with the box b on the upper face ofthe draw-head, provided with the levers k k,jointed together, pivoted to the upper face ot' the draw-head, and provided near their outer ends with the rods mm, passing through holes in the anged face ofthe drawhead, substantially as described.

2. The combination, with draw-head a, provided with holes in its upper and lower face for the passage of the coupling-pin, ot' the elbow-levers 7c 7c', pivoted to the upper face of the draw-head andjointed to each other by the pin k and slot 7610, handles k7, arms 755, semicircular at their outer ends, and provided with the pins le, and rods m m. passing through holes in the hanged face ot' the draw-head, substantially as described.

3. The combination, with a draw-head, of the bail n, pivoted thereto and provided with the horizontal bars o o', and levers n2, substantially as described, and for the purpose Set forth.

4. The combination, with a draw-head and bail, n, pivoted thereto, and provided with the horizontal bars 0 0', and levers n2, ofthe springs 19p', substantially as described, and for the pnrpose set forth.

5. The combination, with a. draw-head, a, and a link, l, ofthe spring-dog r, pivoted on a transverse rod secured to the opposite sides of the opening in the draw-head, and composed of the two arms r r2, the latter, r2, bearing on the inner face ofthe top ofthe draw-head, and the former-, r, pressing against the upper face of the rear end ofthe lilik and holding it horizontal, substantially as described.
